This summer

Its summer. For a year it might be a mere season but for us its a season to struggle. The moisture laden hot winds bringing sweat along with  add to it. Using coolers also don't solve the problem as it throws only water giving cooling sensation only in front of it and an unbearable sweat to the people who are not there. This is a season where mothers in india wait for -- to dry the potato chips , to make pickles , to make powdered spices, this 45 degree celsius hot dry summer weather completely removes the moisture from the red chillies making it thus easy to grind. Going out under the sun  is considered an achievement. Taking bath more than one time is a frequent phenomena. This is a time when students rush out for admission in colleges despite the weather. In newspapers toppers for different competitive examinations from different coaching institutes are being colorfully printed thus adds to the sayings of parents to be like them. After a continuous two to three days of hot weather a few droplets of water gives respite. Refrigerators became multipurpose also the changing water on the ice tray. A continuous appreciation for the matkas are being observed which serves for the thirst more efficiently. Despite the hotness of the weather the daily routine does not stop, The regularity of the world do not slow down.           

process control importance

To increase the precision in any industry ie., to increase to increase its accuracy, its efficiency, to limit the process from crossing the safe limit or the required conditions. This is achieved by certain specific arrangement of  different instruments mainly comprises of a measuring device a controller say valve. The most common example is temperature controller in a tank. The First Step is to measure the temperature with help of a sensor like thermometer or thermocouple. The sensor also consists of a transducer which converts the temperature into electrical signal and transmitter which transmits the signal further on. The sensor is followed by a controller where necessary decision is made according to the reading. The controller comprises of a comparator in which we feed a set point. Comparision of measured reading and set point is made and an error is generated. According to the error generated specific set of instruction in form of electrical signals is sent to the actuator which produces the needed pressure forces or electrical signals for the final control element here steam valve.

   The above illustrated procedure is fully automatic and requires no operator after initialising the process. The first advantage is the accuracy and the second is safety.  Process control thus holds an important position in any industry for its efficient working.



  

THE FRAME OF REFERENCE

Sometimes a thought stuck in my mind. Why people think about the well being of their near ones but at the same time just avoid to think about their over well being. Over well being is taking self achievement as a reference frame. I am writing this to put light on this selfless or selfish nature of Human. A selfish because he thinks about their well being knowingly or unknowingly make him to avoid or solve so called problems depicting his self proclaimed behavior. A selfish because it hurts to see someone progressing faster than us and thus indirectly wish to inhibit his growth. Of course another alternative could be to renovate the reference frame told earlier.
 
    To increase this reference frame is this world its activity giving a false realization of happiness. Every single entity in this universe be it a human, an organization, an industry or a society works to renovate its reference frame. Everything is being observed by a critic eye finding single opportunity to judge it. We do or we tend to do everything for being watched with a critic eye. For this writing the reader is the critic. For every critic eye there are certain preferences for what it requires predicting the possible objective for that work and to see whether that objective fulfills. Somewhere this object is furnished by the critic itself thus reducing the error a bit for judgement. Like the examination paper where the students are being questioned thus giving a clear cut objective. Another possible judging error is to see whether that object is fulfilled, Keeping aside certain postulates, Laws in theoretical physics, mathematics where the methods are predefined it is impossible to judge the fulfillment of the objective and its way to fulfill. One possible solution is adopted by employing a certain person who is well verse about the object and could possibly holds a position to be efficient be not perfect. Another method is by taking certain assumptions about the creator knows, his background and his extent. For examination purpose this looks fair but totally fails for the rest.
